Bathroom Remodel Calculator

The honest answer is a range rather than a number, because a budget refresh of a small powder room and a luxury gut of a primary suite can differ by a factor of ten. Size, quality tier, how much of the room you’re touching, whether the plumbing moves and where you live all matter more than any single choice. Enter your own figures above and open the comparison table — it prices the same bathroom across all five quality tiers, which gives you a bracket instead of false precision.

Budget means stock and economy products — a standard alcove tub-shower, a prefabricated vanity, ceramic tile and builder-grade fixtures. Mid-range is mid-grade brands throughout, which is where most remodels land. High-end brings designer finishes, better tile and glass, and more careful installation. Luxury and ultra-luxury mean custom work, premium stone and fixtures, and the labor to match. The tier scales every material line at once, which is why moving up one step changes the total so much more than swapping a single component.

Yes, and it’s the change people underestimate most often. A toilet needs a drain of a particular size at a particular fall, so relocating it usually means opening the floor and sometimes the ceiling of the room below. Showers and vanities bring their own supply and drain work with them. Relocation typically triggers permits and inspection and adds time to the schedule, which raises labor on everything happening around it. Toggle the relocation switch on and off in the calculator and you’ll see the swing on your own numbers.

A straightforward budget or mid-range refresh that keeps the layout usually runs a few weeks; high-end and luxury work with custom tile, glass or stone runs considerably longer, and moving plumbing adds time on top. The calculator shows an estimated range for your selections in the project snapshot. Two things stretch schedules more than the work itself: waiting on materials that have to be ordered, and inspections that have to happen before the walls close up. Ask your contractor when each item needs to be chosen, not just when it needs to be installed.

Ten to twenty percent of the project cost is the range most professionals recommend, and older houses sit at the top of it. Bathrooms hide more surprises than most rooms because water has been running through them for decades — soft subfloor, rotten framing behind the tub, mould in the wall cavity, old galvanised supply lines. The reserve is for those genuine unknowns rather than for changing your mind about the tile halfway through. Set it here and it’s added to the total, so the number you take away already includes the cushion.

The shower or tub is typically the largest single line, with tile and flooring, the vanity and countertop, and the plumbing rough-in close behind. Then come the lines that are easy to forget: demolition and disposal, lighting and electrical, paint and finishing, and the contingency reserve. Labor runs through all of them — on several components it’s the majority of the cost, not the minority. The doughnut chart above splits your own estimate across every line, which is the fastest way to check whether the budget is going where you assumed.

Rarely in full, and modest remodels tend to recoup a larger share of their cost than luxury ones — the return generally falls as the spend rises, which is why the estimate above shows a lower recouped percentage at the higher tiers. Your neighbourhood matters too: a bathroom finished far above the standard of comparable homes nearby is unlikely to be valued at what it cost. If resale is the main motive, a mid-range remodel usually makes more financial sense than a luxury one; if you’re staying put for years, the question is what the room is worth to you rather than to a future buyer. A local agent can tell you what buyers in your area actually expect.
